Belshal are fist-sized, barnacle-like crustaceans that have developed a symbiotic relationship with the Rofalssa stalks of Kasputin Yar. They form a crystalline shell about themselves and deploy a fan-like catching appendage to catch spores, mites, and organic dust. They also absorb water from the Rofalssa stalks, filter it, and exude it as a dense water vapor that collects on the underside of Rofalssa canopies and then precipitates back to ground level to be absorbed by the stalks' root systems all over again.
